DSL Rings

DSL Rings is the multi award winning and patented revolutionary technology that enables Telcos to deliver fast, service enhancing broadband over the existing network, at a fraction of the cost of Fibre to the Home (FTTH), whilst delivering more than enough capacity to bring triple play offers to both urban and rural areas. DSL Rings benefits include:

Next generation superfast broadband at a fraction of the cost of FTTH.

DSL Rings has the potential to help Telcos claim carbon credits for large deployments and requires no new skills, techniques, tools, or equipment for installation. The solution consumes less power, in the network, than fibre.

DSL Rings awards include:

Winner - Fierce Telecom award for Last Mile Innovation

Finalist - Graham Bell Award for Best Communication Solutions

Finalist - San Andreas Award for Most Disruptive Technology

Finalist - World Communications Award Finalist ‘The Innovation Award’

Further Information

Low-cost, simple deployment
DSL Rings is designed and developed to comply with a Telco’s existing copper line infrastructure. It is very easy to deploy since it doesn’t require new technical skills, right-of-way legislation, or trenching. DSL Rings benefits Telcos’ and their customers, by delivering affordable superfast broadband over copper telephone wires at a fraction of the cost of fibre.

Prompt return on investment
Affordable and highly profitable for Telcos, DSL Rings avoids the huge up-front costs of providing fibre infrastructure to people’s homes and business premises, and the years necessary to realise a return on investment. With DSL Rings return on investment maybe realised within 24 months via a ‘pay as you grow’ deployment model which is supported with a low cost, single day installation.

Multiple applications and opportunities
DSL Rings can be deployed in response to demand in rural, suburban and urban locations. DSL Rings works with both conventional backhaul copper to the Central Office/Exchange, using mBonding (mBond) from Genesis Technical Systems, and with Fibre to the Node/Cabinet (FTTC/FTTN) and mbonding between the Node and the Pedestal. It is a great alternative for FTTH or FTTP. DSL Rings is also the ideal platform for deploying small cells. All copper pairs (used and unused) in the network can be aggregated and shared with small cells as well as with individual homes.

Enabling a full range of Internet Protocol and next generation services
DSL Rings is secure and supports Wi-Fi, voice over Internet Protocol (VoIP), high definition Internet Protocol television (HD IPTV), video on demand (VoD) and femtocell backhaul. DSL Rings has been designed to enable encryption as well as QoS management and prioritisation of traffic on a ‘per end user’ basis to meet Service Level Agreements (SLAs).

A comprehensive eco-friendly solution
DSL Rings is extremely environmentally friendly. Reusing copper cabling negates the need to lay new cable which could disrupt road traffic, damage buildings, and may be subject to delays associated with regulatory and statutory requirements (e.g. right-of-way authorisation). Reusing copper saves time, money and energy. Indeed, DSL Rings requires much less mains power in the network than fibre, significantly reducing a Telcos carbon footprint

DSL Rings is a patented network architecture developed by Genesis Technical Systems. Network capacity is optimised in the current ‘tree and branch’ network if the portion of the network from the Central Office (CO) to the pedestal is bonded, or where there is Fibre to the Node (FTTN) and bonded copper from the Node to the pedestal.

Below is a graphical representation of the architecture. Note that the links between the houses are implemented via a passive cross-connect in the Convergence Node (CN). In this way, a single CN design can efficiently manage up to 16 houses in a given ring.

Bonded pairs are used to obtain maximum bandwidth from the central office to the pedestal. The Convergence Node, which is environmentally hardened and line powered via the copper wire from the central office (or Node location), terminates the bonded signals and acts as the gateway node for the subscriber ‘collector’ ring.

As each node in the ring is a full ADM, based on VDSL2, the DSL transmission bandwidth starts at zero again on each individual hop. In most cases the hops back to the pedestal and then to the neighbour’s house are less than 250 meters (<800ft). VDSL2 bandwidth at this distance is about 200 Mb/s (combined upstream & downstream, depending on the VDSL2 chipset manufacturer’s specifications and the quality of the cable).

With DSL Rings there are two paths into and out of each house, each with the potential of carrying up to 200 Mb/s combined. Therefore the bandwidth potential for this scenario is up to 400 Mb/s (200 Mb/s Eastbound and 200 Mb/s Westbound) depending on the number of bonded pairs and the actual distance from the DSLAM to the pedestal. The greater the number of subscribers on the ring, the greater the bandwidth pool available due to the greater number of pairs available for bonding from the pedestal to the central office. Unlike fibre or cable-based alternatives DSL Rings can also provide E911 service when the power is out.

Resilient Packet Ring (RPR – IEEE 802.17) protocol
DSL Rings technology is based on the RPR protocol that provides multiple advantages. The technology enables a fail-safe in that, if a single pair is cut, the traffic goes in the opposite direction around the ring to get to the network gateway node. This is extremely useful for maintenance purposes, as well as for adding and removing houses to/from the ring. This allows for a deployment business case based on customer demand which eliminates the sunken investment in a ‘build it and they will come’-type approach. RPR also provides built in Quality of Service (QoS) for traffic differentiation and managed services as well as an Efficient Multicast (EM) capability that significantly reduces overall ring bandwidth requirements for multicast/broadcast video.
